Can't pass in a deferred to session.run under Python 3

[mjpieters]

The session.run() function has no path for a non-coroutine function being passed in, it'll simply return without calling twisted.react():

requests-threads/requests_threads.py

Lines 61 to 72 in b4d4384

	def run(self, f):
	# Python 3 only.
	if hasattr(inspect, 'iscoroutinefunction'):
	# Is this a coroutine?
	if inspect.iscoroutinefunction(f):
	def w(reactor):
	return self.wrap(f())
	# If so, convert coroutine to Deferred automatically.
	return task.react(w)
	else:
	# Otherwise, run the Deferred.
	return task.react(f)

Under Python 3, line 63 is True, but if line 65 is False (so f is not a coroutine function) , the function ends. Should the else on line 70 be dropped, and lines 71 and 72 unindented?
